You are Lucky one to get such Knowledge
Welcome to our blog hypothetical world If you want to get thrilling,mysterious and fact knowledge,it is best option for you,Subscribe our blog for getting mysterious facts knowledge.Today we are going to discuss the most interesting topic Black hole,we will try to make understand the formation of black hole and start,the death of black hole and start. We try to understand it with recent discovery,So keep in touch;
Our universe is full of mystery. Billion of events happen daily in our universe in a mysterious way,most of them arie still unexplored. When mysterious object like black is discovered, we feel we are unknown to our universe.Lots of research was done to reveal the mystery of black hole, we became success for a limit,its mysterious is still not revealed to us.
Black hole is such types of massive object in universe which even swallow photons particles of light,Once anything is captured can't be escape from black hole either it is light or a space time,Even time doesn't exist in black hole. As we know time is relative and variable, it is fast for less massive object, slow down for high massive object and doesn't exist for extra massive object (Black hole).Density and gravity is the main things that play vital role for the formation of black hole. When we compress any heavy object more than its capacity, it's density and gravity becomes so high that can capture even light, that gives birth to black hole.Let's consider we have a technology from which we can compress Earth to 1cm diameter,Its density and gravity becomes so high, it can be black hole,If we compress our Sun which is 13lakh times greater than Earth up to 2cm it can be changed to black hole but it is not possible.As we know density and gravity play vital role for the formation of black hole but the density of Earth and Sun is not so high as it can be changed to black hole. If we consider a heavy object whose mass is 10million greater than sun is compressed to 1cm can be changed to black hole. Usually black hole forms by the Star. So let's try to understand the formation of star before knowing about formation of black hole.
Formation of star
Star is formed by the gaseous dust and cloud which presence in galaxy. The cloud formed by gas and dust is known as Nebula (Neharika).In Nebula there is high presence of Hydrogen gas about 74℅and 25℅Helium gas.There is presence of other matter in very less quantity. Density starts increasing when the nebula starts to form star.This is first stage of formation of star. When density increases the gravity also increase and due to gravity it starts compressing, Then its temperature also increase. Due to gradually increase in temperature Hydrogen start to convert in Helium,That gives birth to Star.But it takes billion of years to form.Sun is also a star and formed by the same process.
Formation of black hole
As we know the Fuel of star Hydrogen Star to change in Helium due to nuclear reaction. This process continue till the Fuel Hydrogen gas is completely consumed.When the quantity of hydrogen gas is decrease the star becomes cold gradually. When the Fuel is consumed it lose the control of gravity, due to which it changes to massive explosion which is called supernova. After the supernova the residue of the star converts to neutron star.The gravity of neutron star is very high and due to high gravity, it start compressing to its limit.It compressed to these point where it loses connection to time and becomes invisible, that is Black hole. The mass of the black hole is centred into a small center which is called central singularity point. The boundary around it is called event horizon. If anything that is beside the event horizon is safe.if it cross the boundary event horizon, the object will never escape from black hole. Black destroys the atom of object that enter in it and makes invisible.According to Einstein's theory of relativity, Time slows around it and doesn't exist inside it.
Types of black hole
1.Super massive black hole
It is a type of black hole which is formed at the center of galaxy and whose mass is extra massive. It is also known as Stellar mass black hole. There also exists a black hole in our galaxy (milky way)whose mass is 10million times greater than the sun.
Premordial/Small black hole
It is a type of black hole which is not formed by compressing due to its gravity but due to high temperature and break down of its matter.It's mass is less than the sun.
Stephen opinion to black hole
Stephen Hawkins becomes famous whe he got success in his research of black hole, Today we became able to calculate the energy and mass of black hole because of Stephen Hawkins contribution. Despite he was paralyzed since his childhood he got success using his logic, which a normal researchers can get.His contribution to black hole is described below:
He was knowing completely that no things can escape even photon particles of light when it cross event horizon. He started to do his research in event horizon. He found the event horizon acts as a hologram, everything that is happening inside or in event horizon can be known from event horizon. But we are unable to unrevealed its mystery completely,we got limited success.Stephen Hawkins find a formula to calculate the energy of black hole using its area.After the energy calculated its mass can be known from energy mass relation formula of Einstein. He observed that when a black hole swallow an object its mass and energy increase,its size also increase. He found a radiation radiates by the event horizon. He named it as Hawkins radiation. Most of the scientists are engaged to find incompatibility between quantum mechanics and theory of relativity, that will be theory of everything. When scientists were researching black hole applying Einstein's theory of relativity. Stephen Hawkins research it applying Quantum mechanics principles as a result he found Hawkins radiation. He also found when a black hole radiates energy its mass and energy decreases. If a black hole don't swallow any object for long period of time,it will evaporates and becomes disappeared (Death of black hole).
So hello guys what do you think about black hole. Does the time really slow down around it and doesn't exist inside it.
